We report lifetime measurements of the five levels in the 3d(4)(a(5)D)5s e(6)D term in Cr II at an energy around 83 000 cm(-1), and log(gf) values for 38 transitions from the investigated levels. The lifetimes are obtained using time-resolved, laser-induced fluorescence on ions from a laser-produced plasma. Since the levels have the same parity as the low-lying states directly populated in the pla

Objectives: Patients with type 1 diabetes mellitus (T1DM) lack the portal/peripheral insulin gradient, which might diminish insulin stimulation of hepatic lipogenesis and protect against development of nonalcoholic fatty liver disease (NAFLD). We compared liver fat content and insulin sensitivity of hepatic glucose production and lipolysis between overweight T1DM patients and nondiabetic subjects.

Vi väntar oss att konstnärer ska vara kreativa, men erfarna konstnärer är framför allt hantverksskickliga. I allmänhet är konstnärer inte mer kreativa än andra människor. De kompletterar en tradition eller etablerad teoribildning, precis som forskare. Men till skillnad mot forskare som har ett väldefinierat problem med en given om än okänd lösning via en föreskriven metod, arbetar konstnären med ö

Säkerhet är dynamiskt och speciellt så i komplexa säkerhetskritiska verksamheter. När olyckor och incidenter är sällan förekommande i säkerhetskritiska verksamheter kan det ske en långsam och naturlig erosion av säkerhetsmedvetandet och en organisations beteenden kan börja driva mot säkerhetsmarginalerna. Säkerhetskulturen ses som en stark motriktad kraft i ett sådant händelseförlopp. Att organisa

Mixed findings have been made with regard to the long-term predictive validity of antisocial personality disorder (ASPD) on criminal behaviour in samples of substance abusers. A longitudinal record-linkage study of a cohort of 1052 drug abusers admitted 1977-1995 was undertaken. Subjects were recruited from a detoxification and short-term rehabilitation unit in Lund, Sweden, and followed through c

The article provides with an overview over female sociability in eighteenth century Sweden.

Von Willebrand factor (VWF) is an abundant plasma glycoprotein involved in platelet adhesion and aggregation at sites of vascular injury. ADAMTS13 is the sole physiological VWF-cleaving protease, thus regulating the size of thrombus growth. Dysfunctional ADAMTS13 leads to thrombotic thrombocytopenic purpura (TTP), which is either due to mutations (congenital TTP) or auto-antibodies (acquired TTP).

We present the results of a quantum mechanical modelling of the free carrier absorption (FCA) in semiconductor heterolayers. Elastic and inelastic scatterers are considered with emphasis on the interface defects (optical phonons) contributions to the induced photon absorption for elastic (inelastic) scatterers. Various approaches to FCA are also presented (perturbation, Green's function technique)

The Chinese tussah silkworm, Antheraea pernyi (Lepidoptera: Saturniidae) produces a rare dienoic sex pheromone composed of (E,Z)-6,11-hexadecadienal, (E,Z)-6,11-hexadecadienyl acetate and (E,Z)-4,9-tetradecadienyl acetate, and for which the biosynthetic routes are yet unresolved. By means of gland composition analyses and in vivo labeling we evidenced that pheromone biosynthesis towards the immedi

Green fluorescent protein (GFP) is frequently utilized for metal ion detection and quantification. To improve the metal binding potential of GFP, three residues (N146, F165, and L201) were substituted to histidines. Each variant responded differently upon interaction with metal ions. More than 80% of N146H, having the most accessible surface area, could bind to immobilized metal ions. However, onl

Background. Gestational diabetes mellitus (GDM) is associated with both maternal and offspring adverse effects. The World Health Organization (WHO) has recently adopted novel GDM criteria. The aim of this study was to evaluate the former WHO and a simplified version of the new International Association for Diabetes in Pregnancy Study Group (IADPSG) criteria as to prevalence of and risk factors for

Supply chain management includes coordination and motivation of independently operating partners. Therefore, it is important to align logistics structures, processes and incentives, especially when making major changes involving those components. Traditionally, cost, quality, and service have served as prioritized performance indicators for supply chains, but lately risk is also taken into conside

This paper reports on the results of a cross-sectional study that focused on the impact of attitudes, subjective norms and consumer innovativeness on intention to purchase cosmetic products. Beginning with the Theory of Reasoned Action (Ajzen & Fishbein, 1980; Fishbein, 1980; Fishbein & Ajzen, 1975), several models have been proposed to conceptualize the complex behavioral and social proce
